ROTARY Moron.

Specification of Letters Patent.

Patented July 20, 1915.

Application filed December 31, 1913. Serial No. 809,737.

of which the following Yis a specification,l

' reference being had therein to the accompanying drawings. A

My invention relates to rotary motors and more particularly to a motor adapted to travel through a tube with a cleaner, although it may be used for other purposes.

The object .of my invention is to provide an improved motor simple, strong and eiiicient that will withstand the shocks and jars incident to Aits use.

A further object is to so simplifythe construction as to reduce the cost and provide a motor that can be easily assembled and readily takenapart.

' With these and other objects in view my inventionvconsists of the constructions and combinations hereinafter described and set forth in the claims.4

In the accompanying drawings which form a part of this specification Figure l is a longitudinal section of a motor embodyingmy invention; Fig. 2 is 'a longitudinal section taken on the line 2 2 -of Fig. 4; Figs. 3, 4, 5 Aand 6 are cross-sections on the lies 3 3, 4 4, 5 5 and' 6 6 respectively of Fig. 1; Fig. 7 is an end view and Figs. 8 and 9 each show a modification.

In the drawings l represents a casingof uniform bore open at its respective ends and having a stop intermediate of said ends. The :stop may be formed inte ral with the casing,- but in view of the di culty of al- Aways obtaining an accurate bore against the shoulder of .an integral flange Il may form the stop separately from and secure it to the casing. This'can be done in any suitable Way; but I preferably form an annular recess in the casing and expand a ring or section of tubing into said recess forming a stop 2 as particularly shown in Figs. 1, 2

' and 3. This gives a very strong, substantial and 'permanent construction to withstand the. shocks and jars incident to the use of such motors in driving tube cleaners.

motor bearing member 3 is seated against the front side of said stop and is preferably provided with a bushing 4. The rear end of said member has la flange 5 and a plate 6 is seated between said iiange and bushing and said .plate is provided with ports 7. A dowel-pin 8 secures said plate from lrotation. A valve plate 9 having al flange at its inner end-is seated in a recess of said plate 6 with 60 said flange extending between saidplate and the flange 5 of the bearing member; and said valve ,plate is secured to the plate 6 by a screw 10. Said valve plate is provided with ports 11 of successively reducedA 65 size adapted to register with the ports 7 of the plate 6. It will be seen that by loosening the screw 10 the valve plate can be adjusted so that larger or smaller ports 11 of the valve plate will -register with the ports '7 of the plate 6 wherebya greater'or less amount A`of the motive agent will be ady A motor cylinder 12 is seated withinthe casing 1 against the front side of the motor 75 bearing member 3 and is pinned thereto by dewels 13. A motor bearing member 14 is rivets 18 with the balls 19 in said recesses 9 l the balls will roject slightly beyond the outside walls ofP said disks and contact with wear plates 20 thus forming an .easy running bearing; and the disks 17 form a holding member for the balls that permanently keep the balls in assembled posltion so that when the motor is taken apart they will not drop out and be lost. The motor cylinder 12 is provided with a chamber of such dimensions that when the rotary motor memher 21 is mounted therein it'will contact with the walls of the chamber in two places opposite each other forming two oppositely dispcsed'chambers 22 and 23 as particularly shown in Figs. 4 and 6. Piston blades 24 195 seated in recesses of the rotary motor member are adapted to move radialry into the chambers 22 and 23 in a well-known manner. The rotary motor member 21 is provided with a forwardly and rear'wardlyexne tending shaft journaled in said bearing members, the front end of said shaft extending beyond the end. of the motor and pered opening is scre\vthreaded into thecasing within the opposite end of said casing, said tapered opening contacting a corresponding taper of the bearing member 14, such taper being of -an inclination to more securely tighten and hold said member, as

. well as the cylinder 12 and. bearing member 3 in place against the stop 2.

- The motor cylinder is provided with exhaust ports 31 opening vinto ports 32 through the memberlilL which in turn open into an annular chamber 33 formed between said member andthe exhaust head and the motivedagent escapes through ports 34 in said hea Y It will be noted that the rotary motor member may be lirst assembled withthe motor cylinder and bearing members and -then introduced through an end ofthe casing and secured against the Astop by one of said heads; or one of said bearing members' and the cylinder may be first pressed in place against the stop and then the rotary motor member and other bearing member may be introduced and secured.

Fig. 8 shows a modiication in which the stop 2a is made integral with the casing la; and Fig. 9 shows another modification in which a stop 2l is screw-threaded at its rear end to screw-threads 35 that project into the bore of the cylinder l". f Said stop is introduced from the front end of the casing and when the screw-threaded portion has en gaged the threads 35 of the casing .its further rearward movement is prevented by the Unthreaded portion of the stop.
